Abstract: It is provided a monitoring reactor and a method for using the same, belonging to microbiologic electrochemical early-warning technology. The monitoring reactor enriches microorganisms therein before use, and consumes the organic matter. When the organic matter in the monitoring reactor is consumed completely, i.e. the microorganisms are in a starved state, the monitoring reactor is placed in a system to be monitored for monitoring, thereby avoiding the interference of the organic matter in the soil in the monitoring reactor to the electrical signal and improving the monitoring accuracy. Furthermore, since the electrical signal in the monitoring reactor is conducted through the electricigens, the process of generating electricity of the electricigens is a process of growth and propagation of microorganism. This process is less affected by the monitored environment. Therefore, the signal output process is stable, without swell and sag of the electrical signal.
